Disabling EGR and fuel pressure solenoids
So are we supposed to set FAA bit to 1? I think the confusing part is that in order to Disable the EGR/Enabled Ign Advance you need to enable the bit. I'm guessing that is my issue, but I won't be able to test it out for a couple weeks until the car is back together.

Ok...I changed FAA bit 11 to 1 and also changed FCA bit 15 to 0 (to help aleviate my P0446 I keep getting) and It did drop my startup RPMS by quite a bit. My car was actually struggling to stay running when first started. I also noticed about 150rpm idle decrease which is obviously very easy to increase but is there something else to make the warmup RPMS slightly higher now to counteract the other?
I was thinking about looking at the Low Coolant Temp Timing and % Low temp timing trim vs coolant temp but I believe those are only for closed loop.

What is being diffused from the hose we pulled from the EGR/Emission Canister and vent to the atmosphere now? Will our car smell like gas fumes now? 
What will happen if it isn't vented?
I had the throttle hang issue at 3k RPM constantly. I blocked off the EGR and never disabled/removed anything. I thought I had some sort of boost leak. I just horse-shoed a vacuum line from the two nipples on top of the TB and my issue was gone. I'm going to disable the FAA and FCA bits in the ECU and just need to know if I have to actually remove any of the stuff in the diagram above.

You went 11.52 on the stock cat? ...it should be the same as what you are used to. IF anything you can route it to the back of the car.

You should disable the bits in the ecu...also you did have a boost leak, the 2 nipples source the pressure for the egr...vacuum and psi.
You don't have to remove the stuff in the back if you capped off the nipples, however, you might as well...much cleaner and easier to work on the IM if necessary.

The car is catless.. I never said anything about running catted? 
I did have a boost leak after installing the IM & TB from the EGR until I U'd a vacuum line onto both nipples. That is why the idle was so high. Thanks for your help Ryder!

^ I was just making light of you worrying about fumes knowing that you don't have a cat hah. You really shouldn't notice the smell, or any different smells.
When I removed the solenoids, I only left the egr solenoid(no lines attached) The fpr and evap were removed and all lines associated gone. Takes about 1hr ...pretty straight forward.

NOTE: When removing the entire solenoids and hoses disable the following periphery bits.
Periphery 0/FAA:
-EGR(ign advance) Bit 11 disable(some people leave it on, up to you)
Periphery 2/FCA:
- EVAP> Bit 13,14,15 Disable
- EGR > Bit 9 Disable
Periphery 4/FEA:
- FPR> Bit 7 Disable(When you also disable FCA/P2 Bit 15 that will also take care of the FPR)
